Description
本発明は、リング状のフレームの開口にテープを介して板状の被加工物が支持されたフレームユニットを搬送するための搬送装置、この搬送装置が組み込まれた加工装置、及びこの搬送装置を用いる搬送方法に関する。 The present invention relates to a transport device for transporting a frame unit in which a plate-like workpiece is supported via a tape to an opening of a ring-shaped frame, a processing device incorporating this transport device, and this transport device. The present invention relates to a transport method to be used.
半導体ウェーハや光デバイスウェーハ、セラミックスパッケージ基板等を複数のチップへと分割する際には、例えば、これら板状の被加工物に設定される分割予定ライン(ストリート)に沿って、レーザービームを照射したり、回転する環状のブレードを切り込ませたりする(例えば、特許文献1,2等参照)。 When dividing semiconductor wafers, optical device wafers, ceramics package substrates, etc. into multiple chips, for example, irradiate laser beams along the division lines (streets) set on these plate-like workpieces. Or cutting a rotating annular blade (see, for example, Patent Documents 1 and 2).
上述のような方法で被加工物を加工する前には、被加工物よりも径の大きいテープを被加工物に貼り、また、テープの外周部分にリング状のフレームを固定してフレームユニットを形成することが多い。フレームユニットを形成することで、搬送、加工時の衝撃等から被加工物を保護し、更に、被加工物の取り扱い易さを高められる。 Before processing the workpiece by the method as described above, a tape having a diameter larger than that of the workpiece is applied to the workpiece, and a ring-shaped frame is fixed to the outer peripheral portion of the tape to attach the frame unit. Often formed. By forming the frame unit, the workpiece can be protected from impact during transportation and processing, and the ease of handling the workpiece can be enhanced.
ところで、被加工物を加工する際には、テープの貼られていない面が上を向くように、被加工物をチャックテーブル等で保持するのが一般的である。一方で、加工の種類によっては、テープの貼られていない面を下に向けることもある。そのため、フレームユニットを搬送する搬送装置には、フレームユニットの上下を反転できる機能が求められる。 By the way, when processing a workpiece, the workpiece is generally held by a chuck table or the like so that the surface to which the tape is not applied faces upward. On the other hand, depending on the type of processing, the surface on which the tape is not applied may be turned downward. For this reason, a transport device that transports the frame unit is required to have a function that allows the frame unit to be turned upside down.
上述のような反転機能を持つ搬送装置では、フレームユニットを確実に保持できるように、各部に高い剛性が必要となる。しかしながら、例えば、フレームユニットを保持する保持部を、太く、厚い部材で構成すると、カセットに収容されているフレームユニットの上下の隙間が狭い場合に、この隙間に保持部を挿入してフレームユニットを保持できなくなる。 In the transport apparatus having the reversing function as described above, each part needs to have high rigidity so that the frame unit can be securely held. However, for example, if the holding unit that holds the frame unit is formed of a thick and thick member, when the upper and lower gaps of the frame unit accommodated in the cassette are narrow, the holding unit is inserted into this gap to remove the frame unit. It cannot be held.
また、従来の加工装置では、カセットから搬出されたフレームユニットの位置を、ガイドレール等で構成されるセンタリング機構によって合わせた後に、チャックテーブル等へと搬入していた。ところが、このセンタリング機構は、ある程度のスペースを必要とするので、加工装置を小型化する際の妨げになる。 Further, in the conventional processing apparatus, the position of the frame unit carried out from the cassette is adjusted by a centering mechanism constituted by a guide rail or the like, and then carried into a chuck table or the like. However, since this centering mechanism requires a certain amount of space, it becomes an obstacle when the processing apparatus is downsized.
本発明はかかる問題点に鑑みてなされたものであり、その目的とするところは、カセットに収容されたフレームユニットを確実に保持して搬送でき、加工装置の小型化にも適した搬送装置、この搬送装置が組み込まれた加工装置、及びこの搬送装置を用いる搬送方法を提供することである。 The present invention has been made in view of such problems, and the object of the present invention is to convey and hold the frame unit accommodated in the cassette securely, and is suitable for downsizing the processing apparatus, It is to provide a processing apparatus in which the transport apparatus is incorporated, and a transport method using the transport apparatus.
本発明の一態様によれば、リング状のフレームの開口にテープを介して板状の被加工物が支持されたフレームユニットを収容するカセットから該フレームユニットを搬出し、所定の位置まで搬送する搬送装置であって、該フレームの手前側の離れた2か所を上下に挟んで把持可能な2組の挟持部と、該フレームに突き当てられる突き当て部と、を有する保持部と、該保持部を移動させる移動部と、各構成要素を制御する制御部と、を備え、該制御部は、該挟持部で該フレームを把持して該カセットから部分的に引き出し、該挟持部による把持を解除した後、該フレームを該カセットに向かって移動させるように該突き当て部を該フレームに突き当てた状態で、該挟持部によって該フレームを把持して持ち上げ該所定の位置まで搬送するように各構成要素を制御する搬送装置が提供される。 According to one aspect of the present invention, a frame unit is unloaded from a cassette that houses a frame unit in which a plate-like workpiece is supported via a tape in an opening of a ring-shaped frame, and is conveyed to a predetermined position. A holding device having two sets of sandwiching portions that can be gripped by vertically sandwiching two places on the front side of the frame, and an abutting portion that is abutted against the frame; A moving unit that moves the holding unit; and a control unit that controls each component. The control unit grips the frame by the clamping unit and partially pulls the frame from the cassette, and grips by the clamping unit. After the release, the frame is gripped by the clamping unit and lifted to the predetermined position with the abutting part being abutted against the frame so that the frame is moved toward the cassette. In Transfer device for controlling the components is provided.
また、本発明の一態様によれば、被加工物を保持するチャックテーブルと、該チャックテーブルに保持された被加工物を加工する加工ユニットと、該カセットが載置されるカセット載置領域と、該カセットから該フレームユニットを搬出して該チャックテーブルまで搬送する搬送ユニットと、を備え、該搬送ユニットは、請求項1に記載の搬送装置である加工装置が提供される。 According to another aspect of the present invention, a chuck table that holds a workpiece, a processing unit that processes the workpiece held on the chuck table, and a cassette placement area on which the cassette is placed; A conveying unit that unloads the frame unit from the cassette and conveys the frame unit to the chuck table, wherein the conveying unit is provided with a processing device that is a conveying device according to claim 1.
また、本発明の一態様によれば、リング状のフレームの開口にテープを介して板状の被加工物が支持されたフレームユニットを収容するカセットから該フレームユニットを搬出し、所定の位置まで搬送する搬送方法であって、該フレームの手前側の離れた2か所を上下に挟んで把持可能な2組の挟持部と、該フレームに突き当てられる突き当て部と、を有する保持部と、該保持部を移動させる移動部と、各構成要素を制御する制御部と、を備える搬送装置を用い、該2組の挟持部の一方又は双方で該フレームを把持して該カセットから部分的に引き出し、該2組の挟持部の一方又は双方による把持を解除してから、該フレームを該カセットに向かって移動させるように該突き当て部を該フレームに突き当て、該突き当て部が該フレームに突き当てられた状態で、該2組の挟持部によって該フレームを把持して持ち上げ該所定の位置まで搬送する搬送方法が提供される。 Further, according to one aspect of the present invention, the frame unit is unloaded from the cassette that houses the frame unit in which the plate-shaped workpiece is supported via the tape in the opening of the ring-shaped frame, and is moved to a predetermined position. A holding method having two sets of holding portions that can be gripped by vertically holding two places on the front side of the frame, and an abutting portion that is abutted against the frame. And using a transfer device that includes a moving unit that moves the holding unit and a control unit that controls each component, and grips the frame with one or both of the two sets of clamping units and partially removes the frame from the cassette. And the gripping part is released from one or both of the two sets of clamping parts, and then the abutting part is abutted against the frame so that the frame is moved toward the cassette. Thrust into the frame Temple state, transporting method for transporting to said predetermined raised position by grasping the frame is provided by the two pairs of clamping portions.
本発明の一態様に係る搬送装置は、フレームの手前側の離れた2か所を上下に挟んで把持可能な2組の挟持部と、フレームに突き当てられる突き当て部と、を有している。そのため、挟持部でフレームを把持してカセットから部分的に引き出し、挟持部による把持を解除した後、フレームをカセットに向かって移動させるように突き当て部をフレームに突き当てた状態で、挟持部によってフレームを把持して持ち上げることで、カセットに収容されたフレームユニットを確実に保持して搬送できる。 The conveyance device according to one aspect of the present invention includes two sets of clamping portions that can be gripped by vertically sandwiching two places on the front side of the frame, and an abutting portion that is abutted against the frame. Yes. Therefore, after holding the frame with the holding part and partially pulling it out from the cassette, after releasing the holding by the holding part, the holding part with the abutting part hitting the frame so as to move the frame toward the cassette By gripping and lifting the frame, the frame unit accommodated in the cassette can be securely held and transported.
すなわち、2組の挟持部によってフレームの離れた2か所を把持するので、フレームを1か所で把持する場合に比べてフレームの撓みが抑制され、フレームユニットを安定させることができる。これにより、フレームユニットを確実に保持でき、また、フレームユニットの反転も容易になる。 That is, since the two places of the frame are gripped by the two sets of sandwiching portions, the frame is restrained from being bent as compared with the case where the frame is gripped at one place, and the frame unit can be stabilized. Thereby, the frame unit can be securely held, and the frame unit can be easily reversed.
また、突き当て部をフレームに突き当ててフレームユニットの位置が決まった状態で、挟持部によってフレームを把持して搬送するので、従来のようなセンタリング機構でフレームユニットの位置を合わせる必要がない。つまり、ある程度のスペースを必要とするセンタリング機構を加工装置に設ける必要がなくなるので、加工装置の小型化にも適している。 Further, since the frame is gripped and transported by the holding portion in a state where the abutment portion is abutted against the frame and the position of the frame unit is determined, it is not necessary to align the position of the frame unit with a conventional centering mechanism. That is, since it is not necessary to provide the machining apparatus with a centering mechanism that requires a certain amount of space, it is also suitable for downsizing the machining apparatus.
このように、本発明の一態様によれば、カセットに収容されたフレームユニットを確実に保持して搬送でき、加工装置の小型化にも適した搬送装置、この搬送装置が組み込まれた加工装置、及びこの搬送装置を用いる搬送方法を提供できる。 As described above, according to one aspect of the present invention, a transport device that can reliably hold and transport the frame unit accommodated in the cassette and is suitable for downsizing the processing device, and a processing device in which the transport device is incorporated. And a transport method using the transport device.

また、保持ハンドフレーム22は、第1部分24の第1突き当て面24a側の両端から斜めに突出する第2部分26及び第3部分28を有している。第2部分26及び第3部分28の第1突き当て面24a側の側面は、それぞれ、搬送の際にフレームユニット1に突き当てられる第2突き当て面(突き当て部)26a及び第3突き当て面(突き当て部)28aとなる。 The holding hand frame 22 has a second portion 26 and a third portion 28 that project obliquely from both ends of the first portion 24 on the first abutting surface 24a side. The side surfaces of the second portion 26 and the third portion 28 on the first abutting surface 24a side are respectively a second abutting surface (abutting portion) 26a and a third abutting surface that are abutted against the frame unit 1 during transport. It becomes the surface (butting part) 28a.
第2部分26の第2突き当て面26a側、及び第3部分28の第3突き当て面28a側には、それぞれ、フレームユニット1を把持するための挟持爪(挟持部)30及び挟持爪(挟持部)32が設けられている。挟持爪30及び挟持爪32は、それぞれ、上爪及び下爪を有しており、フレームユニット1内のフレーム23(図2(A)等参照)を上下に挟んで把持できる。 On the second abutting surface 26a side of the second portion 26 and on the third abutting surface 28a side of the third portion 28, respectively, a clamping claw (clamping portion) 30 and a clamping claw (for holding the frame unit 1) A clamping part) 32 is provided. Each of the holding claws 30 and the holding claws 32 has an upper claw and a lower claw, and can hold the frame 23 (see FIG. 2A, etc.) in the frame unit 1 by holding it vertically.
搬送ユニット10には、搬送ユニット10の各構成要素を制御するための制御ユニット(制御部)34が接続されている。この制御ユニット34の機能は、後に詳述する。なお、本実施形態では、搬送ユニット10を制御するための専用の制御ユニット34を例示しているが、レーザー加工装置2の各構成要素を制御するための制御ユニット(不図示)を搬送ユニット10の制御に用いることもできる。 A control unit (control unit) 34 for controlling each component of the transport unit 10 is connected to the transport unit 10. The function of the control unit 34 will be described in detail later. In the present embodiment, a dedicated control unit 34 for controlling the transport unit 10 is illustrated, but a control unit (not shown) for controlling each component of the laser processing apparatus 2 is used as the transport unit 10. It can also be used for the control.
搬送ユニット10の後方には、チャックテーブル移動機構36が設けられている。チャックテーブル移動機構36は、Y軸方向(割り出し送り方向)に移動するY軸移動テーブル38と、Y軸移動テーブル38の上面に配置され、X軸方向(加工送り方向)に移動するX軸移動テーブル40とを備えている。 A chuck table moving mechanism 36 is provided behind the transport unit 10. The chuck table moving mechanism 36 is disposed on the upper surface of the Y-axis moving table 38 that moves in the Y-axis direction (index feed direction) and the X-axis movement that moves in the X-axis direction (machining feed direction). And a table 40.
X軸移動テーブル40の上面側には、フレームユニット1内の被加工物11を保持するためのチャックテーブル42が配置されている。また、チャックテーブル42の周囲には、フレームユニット1を構成するフレーム23を固定するための複数のクランプ44が設けられている。 On the upper surface side of the X-axis moving table 40, a chuck table 42 for holding the workpiece 11 in the frame unit 1 is disposed. A plurality of clamps 44 for fixing the frame 23 constituting the frame unit 1 are provided around the chuck table 42.
チャックテーブル42は、モータ等の回転駆動源(不図示)に連結されており、Z軸方向(鉛直方向)に概ね平行な回転軸の周りに回転する。上述したチャックテーブル移動機構36でY軸移動テーブル38をY軸方向に移動させれば、チャックテーブル42はY軸方向に割り出し送りされ、X軸移動テーブル40をX軸方向に移動させれば、チャックテーブル42はX軸方向に加工送りされる。 The chuck table 42 is connected to a rotation drive source (not shown) such as a motor, and rotates around a rotation axis substantially parallel to the Z-axis direction (vertical direction). If the Y-axis moving table 38 is moved in the Y-axis direction by the chuck table moving mechanism 36 described above, the chuck table 42 is indexed and fed in the Y-axis direction, and if the X-axis moving table 40 is moved in the X-axis direction, The chuck table 42 is processed and fed in the X-axis direction.
チャックテーブル42の上面は、被加工物11を保持するための保持面42aになっている。この保持面42aは、チャックテーブル42の内部に形成された吸引路(不図示)等を通じて吸引源(不図示)に接続されている。例えば、搬送ユニット10で搬送されたフレームユニット1(被加工物11)を保持面42aに載せ、吸引源の負圧を作用させれば、被加工物11をチャックテーブル42で吸引、保持できる。 The upper surface of the chuck table 42 is a holding surface 42 a for holding the workpiece 11. The holding surface 42 a is connected to a suction source (not shown) through a suction path (not shown) formed inside the chuck table 42. For example, the workpiece 11 can be sucked and held by the chuck table 42 by placing the frame unit 1 (workpiece 11) transferred by the transfer unit 10 on the holding surface 42a and applying a negative pressure of a suction source.
なお、本実施形態では、フレームユニット1を搬送ユニット10でチャックテーブル42の保持面42aに載せているが、例えば、チャックテーブル42の手前に仮置きテーブルを配置し、この仮置きテーブルにフレームユニット1を載せるようにしても良い。この場合には、例えば、搬送ユニット10とは別の搬送ユニットを用いて、フレームユニット1を仮置きテーブルからチャックテーブル42へと搬送できる。 In this embodiment, the frame unit 1 is placed on the holding surface 42a of the chuck table 42 by the transport unit 10, but for example, a temporary table is arranged in front of the chuck table 42, and the frame unit is placed on the temporary table. 1 may be placed. In this case, for example, the frame unit 1 can be transported from the temporary placement table to the chuck table 42 using a transport unit different from the transport unit 10.
チャックテーブル移動機構36の側方には、柱状の支持構造46が設けられている。支持構造46は、チャックテーブル移動機構36側に突出する支持アーム48を備えており、この支持アーム48の先端部には、下方に向けてレーザービームを照射するレーザー加工ユニット(加工ユニット)50が配置されている。 A columnar support structure 46 is provided on the side of the chuck table moving mechanism 36. The support structure 46 includes a support arm 48 that protrudes toward the chuck table moving mechanism 36, and a laser processing unit (processing unit) 50 that irradiates a laser beam downward is provided at the tip of the support arm 48. Has been placed.
レーザー加工ユニット50は、レーザー発振器(不図示)で発振されるレーザービームを集光用のレンズ52で集光してチャックテーブル42上の被加工物11に照射する。そのため、例えば、レーザー加工ユニット50でレーザービームを照射しながら、チャックテーブル42をX軸方向に加工送りさせることで、被加工物11をX軸方向に沿ってレーザー加工できる。 The laser processing unit 50 condenses a laser beam oscillated by a laser oscillator (not shown) by a condensing lens 52 and irradiates the workpiece 11 on the chuck table 42. Therefore, for example, the workpiece 11 can be laser processed along the X-axis direction by feeding the chuck table 42 in the X-axis direction while irradiating the laser beam with the laser processing unit 50.
なお、レーザー加工ユニット50の構成等は、採用される加工方法等に応じて適切に設定、変更される。例えば、被加工物11の内部を多光子吸収で改質して改質された領域(改質層)を形成したい場合には、被加工物11を透過する波長のレーザービームを発振できるレーザー発振器がレーザー加工ユニット50に組み込まれる。 The configuration and the like of the laser processing unit 50 are appropriately set and changed according to the processing method employed. For example, when it is desired to form a modified region (modified layer) by modifying the inside of the workpiece 11 by multiphoton absorption, a laser oscillator capable of oscillating a laser beam having a wavelength that passes through the workpiece 11 Is incorporated into the laser processing unit 50.
また、被加工物11をレーザーアブレーションで加工したい場合には、被加工物11に吸収される波長のレーザービームを発振できるレーザー発振器がレーザー加工ユニット50に組み込まれる。加工後の被加工物11(フレームユニット1)は、例えば、搬送ユニット10を用いてカセット6に搬入される。 Further, when it is desired to process the workpiece 11 by laser ablation, a laser oscillator capable of oscillating a laser beam having a wavelength absorbed by the workpiece 11 is incorporated in the laser processing unit 50. The processed workpiece 11 (frame unit 1) after processing is carried into the cassette 6 by using the transport unit 10, for example.
上述した搬送ユニット10(制御ユニット34)、チャックテーブル移動機構36、チャックテーブル42、レーザー加工ユニット50等の構成要素は、レーザー加工装置2の全体を制御するための制御ユニット(不図示)に接続されている。この制御ユニットは、被加工物11が適切に加工されるように各構成要素の動作を制御する。 The components such as the transport unit 10 (control unit 34), the chuck table moving mechanism 36, the chuck table 42, and the laser processing unit 50 described above are connected to a control unit (not shown) for controlling the entire laser processing apparatus 2. Has been. This control unit controls the operation of each component so that the workpiece 11 is processed appropriately.

A ring-shaped frame 23 is fixed to the outer peripheral portion of the tape 21. That is, the workpiece 11 is supported via the tape 21 in the opening 23 a of the frame 23, and the frame unit 1 in which the workpiece 11, the tape 21, and the frame 23 are integrated is formed.
一方で、図2(B)に示す第2形態では、被加工物11の裏面11b側に、被加工物11よりも径の大きいテープ21が貼られている。また、テープ21の外周部分には、リング状のフレーム23が固定されている。すなわち、フレーム23の開口23aには、テープ21を介して被加工物11が支持されており、被加工物11、テープ21及びフレーム23が一体となったフレームユニット1が形成されている。 On the other hand, in the second embodiment shown in FIG. 2B, a tape 21 having a diameter larger than that of the workpiece 11 is attached to the back surface 11b side of the workpiece 11. A ring-shaped frame 23 is fixed to the outer peripheral portion of the tape 21. That is, the workpiece 11 is supported via the tape 21 in the opening 23 a of the frame 23, and the frame unit 1 in which the workpiece 11, the tape 21, and the frame 23 are integrated is formed.
次に、上述したフレームユニット1を収容するためのカセット6の構成例について説明する。図3は、カセット6の構成例を模式的に示す斜視図である。カセット6は、互いの内側面が向き合うように配置された一対の側板部62,64を有している。各側板部62,64の内側面には、それぞれ、水平方向に延びる複数の棚板部62a,64aが鉛直方向に沿って概ね等しい間隔で配置されている。 Next, a configuration example of the cassette 6 for housing the frame unit 1 described above will be described. FIG. 3 is a perspective view schematically showing a configuration example of the cassette 6. The cassette 6 has a pair of side plate portions 62 and 64 arranged so that the inner side surfaces thereof face each other. On the inner side surfaces of the side plate portions 62 and 64, a plurality of shelf plate portions 62a and 64a extending in the horizontal direction are arranged at substantially equal intervals along the vertical direction.
複数の棚板部62a,64aは、各側板部62,64の対応する高さの位置に設けられている。対応する高さの一対の棚板部62a,64aによって、1個のフレームユニット1が支持される。具体的には、フレームユニット1を構成するフレーム23の一部が、一対の棚板部62a,64aによって支持される。なお、この側板部62,64は、天板部66、底板部68、及び背板部70(図4(A)等参照)により接続されている。 The plurality of shelf plates 62a and 64a are provided at corresponding height positions of the side plates 62 and 64, respectively. One frame unit 1 is supported by a pair of shelf boards 62a and 64a having a corresponding height. Specifically, a part of the frame 23 constituting the frame unit 1 is supported by a pair of shelf plates 62a and 64a. The side plate portions 62 and 64 are connected by a top plate portion 66, a bottom plate portion 68, and a back plate portion 70 (see FIG. 4A, etc.).
上述のように構成された搬送ユニット10でフレームユニット1を搬送する搬送方法について説明する。本実施形態では、まず、カセット6に収容されたフレームユニット1のフレーム23を2組の挟持爪30,32で把持して、フレームユニット1をカセット6から部分的に引き出す(引き出しステップ)。図4(A)及び図4(B)は、フレームユニット1がカセット6から部分的に引き出される様子を説明するための一部断面平面図である。 A transport method for transporting the frame unit 1 by the transport unit 10 configured as described above will be described. In this embodiment, first, the frame 23 of the frame unit 1 accommodated in the cassette 6 is gripped by the two sets of clamping claws 30 and 32, and the frame unit 1 is partially pulled out from the cassette 6 (drawing step). 4A and 4B are partial cross-sectional plan views for explaining a state in which the frame unit 1 is partially pulled out from the cassette 6.
フレームユニット1をカセット6から部分的に引き出す際には、まず、制御ユニット34が昇降機構12を作動させて、対象のフレームユニット1の高さに保持ハンド20の高さを合わせる。次に、制御ユニット34は、搬送アーム14を作動させて、図4(A)に示すように、挟持爪30,32でフレーム23の手前側の離れた2か所を把持できる位置まで保持ハンド20を移動させる。 When partially pulling out the frame unit 1 from the cassette 6, first, the control unit 34 operates the lifting mechanism 12 to adjust the height of the holding hand 20 to the height of the target frame unit 1. Next, the control unit 34 operates the transfer arm 14 to hold the holding hand to a position where the holding claws 30 and 32 can grip two positions apart on the front side of the frame 23 as shown in FIG. 20 is moved.
その後、制御ユニット34は、挟持爪30,32にフレーム23の手前側の離れた2か所を把持させる。そして、再び搬送アーム14を作動させて、図4(B)に示すように、フレームユニット1をある程度の位置まで引き出す。フレームユニット1の引き出し量は、例えば、挟持爪30,32での把持を解除してもフレームユニット1がカセット6から脱落せず、また、後にフレームユニット1に対して第1突き当て面24a等を適切に突き当てられる範囲で調整される。 After that, the control unit 34 causes the holding claws 30 and 32 to grip two positions away from the front side of the frame 23. Then, the transfer arm 14 is operated again, and the frame unit 1 is pulled out to a certain position as shown in FIG. The amount of the frame unit 1 to be pulled out is such that, for example, the frame unit 1 does not fall out of the cassette 6 even if the holding claws 30 and 32 are released, and the first abutting surface 24a etc. Is adjusted within the range that can be properly abutted.
上述のようにフレームユニット1をカセット6から部分的に引き出した後に、制御ユニット34は、挟持爪30,32によるフレーム23の把持を解除する。また、フレームユニット1(フレーム23)をカセット6の内部へと向かって移動させるように、保持ハンド20の第1突き当て面24a、第2突き当て面26a、及び第3突き当て面28aを、フレーム23の手前側に突き当てる(突き当てステップ)。 After partially pulling out the frame unit 1 from the cassette 6 as described above, the control unit 34 releases the gripping of the frame 23 by the clamping claws 30 and 32. Further, the first abutting surface 24a, the second abutting surface 26a, and the third abutting surface 28a of the holding hand 20 are arranged so as to move the frame unit 1 (frame 23) toward the inside of the cassette 6. It abuts on the near side of the frame 23 (abutment step).
図5(A)は、第1突き当て面24a、第2突き当て面26a、及び第3突き当て面28a(以下、第1突き当て面24a等)がフレーム23の手前側に突き当てられる様子を説明するための一部断面平面図である。第1突き当て面24a等をフレーム23の手前側に突き当てる際には、制御ユニット34は、まず、搬送アーム14を作動させて、保持ハンド20をカセット6に向かって移動させる。 5A shows a state in which the first butting surface 24a, the second butting surface 26a, and the third butting surface 28a (hereinafter, the first butting surface 24a and the like) are butted against the front side of the frame 23. It is a partial cross section top view for demonstrating. When the first abutting surface 24 a and the like are abutted against the front side of the frame 23, the control unit 34 first operates the transport arm 14 to move the holding hand 20 toward the cassette 6.
その後、図5(A)に示すように、第1突き当て面24a等がフレーム23の手前側に突き当てられ、フレームユニット1がカセット6の内部へと向かって僅かに移動すると、制御ユニット34は、搬送アーム14を停止させる。そして、この状態で、挟持爪30,32にフレーム23の手前側の離れた2か所を把持させる。 Thereafter, as shown in FIG. 5A, when the first abutting surface 24a and the like are abutted against the front side of the frame 23 and the frame unit 1 moves slightly toward the inside of the cassette 6, the control unit 34 Stops the transfer arm 14. Then, in this state, the holding claws 30 and 32 are made to grip two places away from the front side of the frame 23.
このように、本実施形態では、フレームユニット1を部分的に引き出した後に、第1突き当て面24a等をフレーム23の手前側に突き当てるので、保持ハンド20をカセット6の内部の深い位置まで侵入させなくても、フレームユニット1を適切に把持できる。つまり、フレームユニット1の上下の隙間が狭い場合等でも、フレームユニット1を適切に保持して搬送できる。 Thus, in this embodiment, after the frame unit 1 is partially pulled out, the first abutting surface 24 a and the like are abutted against the near side of the frame 23, so that the holding hand 20 is brought to a deep position inside the cassette 6. The frame unit 1 can be properly gripped without intrusion. That is, even when the upper and lower gaps of the frame unit 1 are narrow, the frame unit 1 can be appropriately held and transported.
第1突き当て面24a等がフレーム23の手前側に突き当てられた状態で、挟持爪30,32にフレーム23の手前側の離れた2か所を把持させた後には、フレームユニット1(フレーム23)を僅かに持ち上げ、所定の位置まで搬送する(搬送ステップ)。図5(B)は、フレームユニット1が搬送される様子を説明するための一部断面平面図である。 After the first butting surfaces 24a and the like are abutted against the front side of the frame 23, the holding claws 30 and 32 are gripped at two locations apart on the near side of the frame 23, and then the frame unit 1 (frame 23) is slightly lifted and transported to a predetermined position (transport step). FIG. 5B is a partial cross-sectional plan view for explaining how the frame unit 1 is conveyed.
フレームユニット1を所定の位置まで搬送する際には、まず、制御ユニット34が昇降機構12を作動させて、フレームユニット1を僅かに上昇させる。その後、図5(B)に示すように、搬送アーム14を作動させて、フレームユニット1をカセット6から完全に引き出す。そして、所定の位置(例えば、チャックテーブル42)までフレームユニット1を搬送する。 When transporting the frame unit 1 to a predetermined position, first, the control unit 34 operates the lifting mechanism 12 to slightly raise the frame unit 1. After that, as shown in FIG. 5B, the transport arm 14 is operated to completely pull out the frame unit 1 from the cassette 6. Then, the frame unit 1 is transported to a predetermined position (for example, the chuck table 42).
以上のように、本実施態様に係る搬送ユニット(搬送装置)10は、フレーム23の手前側の離れた2か所を上下に挟んで把持可能な2組の挟持爪(挟持部)30,32と、フレーム23に突き当てられる第1突き当て面(突き当て部)24a、第2突き当て面(突き当て部)26a、及び第3突き当て面(突き当て部)28aと、を有している。 As described above, the conveyance unit (conveyance device) 10 according to this embodiment has two sets of clamping claws (clamping portions) 30 and 32 that can be gripped by vertically sandwiching two distant locations on the front side of the frame 23. And a first butting surface (butting portion) 24a butted against the frame 23, a second butting surface (butting portion) 26a, and a third butting surface (butting portion) 28a. Yes.
そのため、挟持爪30,32でフレーム23を把持してカセット6から部分的に引き出し、挟持爪30,32による把持を解除した後、フレーム23をカセット6に向かって移動させるように第1突き当て面24a、第2突き当て面26a、及び第3突き当て面28aをフレーム23に突き当てた状態で、挟持爪30,32によってフレーム23を把持して持ち上げることで、カセット6に収容されたフレームユニット1を確実に保持して搬送できる。 For this reason, the frame 23 is gripped by the clamping claws 30 and 32 and partially pulled out from the cassette 6. After the gripping by the clamping claws 30 and 32 is released, the first abutment is performed so that the frame 23 is moved toward the cassette 6. The frame accommodated in the cassette 6 by gripping and lifting the frame 23 by the clamping claws 30 and 32 in a state where the surface 24a, the second butting surface 26a and the third butting surface 28a are butted against the frame 23. The unit 1 can be securely held and transported.
すなわち、2組の挟持爪30,32によってフレーム23の離れた2か所を把持するので、フレーム23を1か所で把持する場合に比べてフレーム23の撓みが抑制され、フレームユニット1を安定させることができる。これにより、フレームユニット1を確実に保持でき、また、フレームユニット1の反転も容易になる。 That is, since the two gripping claws 30 and 32 hold the two places away from the frame 23, the bending of the frame 23 is suppressed compared to the case where the frame 23 is held at one place, and the frame unit 1 is stabilized. Can be made. As a result, the frame unit 1 can be securely held, and the frame unit 1 can be easily reversed.
また、第1突き当て面24a、第2突き当て面26a、及び第3突き当て面28aをフレーム23に突き当ててフレームユニット1の位置が決まった状態で、挟持爪30,32によってフレーム23を把持して搬送するので、従来のようなセンタリング機構でフレームユニット1の位置を合わせる必要がない。つまり、ある程度のスペースを必要とするセンタリング機構を加工装置に設ける必要がなくなるので、レーザー加工装置(加工装置)2の小型化にも適している。 Further, the frame 23 is held by the holding claws 30 and 32 in a state where the position of the frame unit 1 is determined by abutting the first abutting surface 24a, the second abutting surface 26a, and the third abutting surface 28a against the frame 23. Since it is gripped and conveyed, it is not necessary to align the position of the frame unit 1 with a conventional centering mechanism. That is, since it is not necessary to provide a centering mechanism that requires a certain amount of space in the processing apparatus, the laser processing apparatus (processing apparatus) 2 is suitable for downsizing.
なお、本発明は、上記実施形態の記載に制限されず種々変更して実施可能である。例えば、上記実施形態では、フレームユニット1をカセット6から部分的に引き出す際に、フレーム23を2組の挟持爪30,32で把持しているが、挟持爪30及び挟持爪32のいずれか一方でフレーム23を把持することもできる。 In addition, this invention is not restrict | limited to description of the said embodiment, A various change can be implemented. For example, in the above embodiment, when the frame unit 1 is partially pulled out from the cassette 6, the frame 23 is gripped by the two pairs of clamping claws 30 and 32, but either the clamping claw 30 or the clamping claw 32 is held. The frame 23 can also be gripped by.
図6(A)は、フレームユニット1がカセット6から部分的に引き出される際に、フレーム23を挟持爪32によって把持する様子を説明するための一部断面平面図である。この場合、制御ユニット34は、搬送アーム14を作動させて、挟持爪32でフレーム23の手前側の1か所を把持できる位置まで保持ハンド20を移動させる。 FIG. 6A is a partial cross-sectional plan view for explaining how the frame 23 is gripped by the clamping claws 32 when the frame unit 1 is partially pulled out from the cassette 6. In this case, the control unit 34 operates the transport arm 14 to move the holding hand 20 to a position where the holding claw 32 can grip one position on the near side of the frame 23.
その後、制御ユニット34は、挟持爪32にフレーム23の手前側の1か所を把持させる。そして、再び搬送アーム14を作動させて、フレームユニット1をある程度の位置まで引き出す。この場合には、カセット6の内部に挟持爪32の一部を侵入させるだけで良いので、フレームユニット1の上下の隙間がより狭い場合等でも、フレームユニット1を適切に引き出すことができる。 Thereafter, the control unit 34 causes the clamping claw 32 to grip one location on the near side of the frame 23. Then, the transfer arm 14 is operated again, and the frame unit 1 is pulled out to a certain position. In this case, it is only necessary to allow a part of the clamping claws 32 to enter the inside of the cassette 6, so that the frame unit 1 can be properly pulled out even when the upper and lower gaps of the frame unit 1 are narrower.
なお、この場合には、カセット6の内部に侵入させる挟持爪32の一部を薄く形成しておくと良い。図6(B)は、一部が薄く形成された挟持爪32について説明するための図である。図6(B)に示すように、挟持爪32は、上爪82と下爪84とを有している。上爪82の中央部82a及び下爪84の中央部84aは、剛性を確保できるように厚く形成されている。 In this case, it is preferable that a part of the clamping claw 32 that enters the inside of the cassette 6 is formed thin. FIG. 6B is a diagram for explaining the sandwiching claws 32 that are partially formed thin. As shown in FIG. 6B, the clamping claw 32 has an upper claw 82 and a lower claw 84. The central portion 82a of the upper claw 82 and the central portion 84a of the lower claw 84 are formed thick so as to ensure rigidity.
一方で、上爪82の先端部82b及び下爪84の先端部84bは、中央部82a及び中央部84aに比べて薄く形成されている。フレームユニット1をカセット6から部分的に引き出す際には、この上爪82の先端部82bと下爪84の先端部84bとをカセット6の内部に挿入して、先端部82bと先端部84bとでフレーム23を把持すれば良い。この場合、フレームユニット1の上下の隙間が更に狭い場合等でも、フレームユニット1を適切に引き出すことができる。なお、ここでは、挟持爪32を用いる場合についてのみ説明したが、反対側の挟持爪30を用いる場合も同様である。 On the other hand, the front end portion 82b of the upper claw 82 and the front end portion 84b of the lower claw 84 are formed thinner than the central portion 82a and the central portion 84a. When the frame unit 1 is partially pulled out from the cassette 6, the tip 82b of the upper claw 82 and the tip 84b of the lower claw 84 are inserted into the cassette 6, and the tip 82b and the tip 84b The frame 23 may be gripped with In this case, the frame unit 1 can be pulled out appropriately even when the upper and lower gaps of the frame unit 1 are narrower. Here, only the case of using the clamping claws 32 has been described, but the same applies to the case of using the clamping claws 30 on the opposite side.
